Low Power, 3V to 36V, Single/Dual/Quad Amplifiers
The COMLINEAR CLC1050 (single), CLC2050 (dual), and CLC4050 (quad)
are voltage feedback amplifiers that are internally frequency compensated to
provide unity gain stability. At unity gain (G=1), these amplifiers offer 550kHz
of bandwidth. They consume only 0.5mA of supply current over the entire
power supply operating range. The CLC1050, CLC2050, and CLC4050 are
specifically designed to operate from single or dual supply voltages.
The COMLINEAR CLC1050, CLC2050, and CLC4050 offer a common mode
voltage range that includes ground and a wide output voltage swing. The
combination of low-power, high supply voltage range, and low supply current
make these amplifiers well suited for many general purpose applications and
as alternatives to several industry standard amplifiers on the market today.

Notes:
1. 100% tested at 25°C. (Limits over the full temperature range are guaranteed by design.)
2. The input common mode voltage of either input signal voltage should be kept > 0.3V at 25°C. The upper end of the common-mode voltage range is +VS - 1.5V at
25°C, but either or both inputs can go to +36V without damages, independent of the magnitude of VS.

Power Dissipation
Basic Operation
Power dissipation should not be a factor when operating
under the stated 2k ohm load condition. However, applications with low impedance, DC coupled loads should
be analyzed to ensure that maximum allowed junction
temperature is not exceeded. Guidelines listed below can
be used to verify that the particular application will not
cause the device to operate beyond it’s intended operating range.
Figures 1, 2, and 3 illustrate typical circuit configurations for
non-inverting, inverting, and unity gain topologies for dual
supply applications. They show the recommended bypass
capacitor values and overall closed loop gain equations.

PD = Psupply - Pload
Psupply = Vsupply × IRMS supply

In order to determine PD, the power dissipated in the load
needs to be subtracted from the total power delivered by
the supplies.
Supply power is calculated by the standard power equation.

Where TAmbient is the temperature of the working environment.
G = 1 + (Rf/Rg)

Maximum power levels are set by the absolute maximum
junction rating of 150°C. To calculate the junction temperature, the package thermal resistance value ThetaJA
(ӨJA) is used along with the total die power dissipation.
G=1
Figure 3. Unity Gain Circuit
These measurements are basic and are relatively easy to
perform with standard lab equipment. For design purposes
however, prior knowledge of actual signal levels and load
impedance is needed to determine the dissipated power.
Here, PD can be found from
PD = PQuiescent + PDynamic - PLoad
Quiescent power can be derived from the specified IS values along with known supply voltage, VSupply. Load power
can be calculated as above with the desired signal amplitudes using:

For a given load capacitance, adjust RS to optimize the
tradeoff between settling time and bandwidth. In general,
reducing RS will increase bandwidth at the expense of additional overshoot and ringing.

Ambient Temperature (°C)
An overdrive condition is defined as the point when either one of the inputs or the output exceed their specified
voltage range. Overdrive recovery is the time needed for
the amplifier to return to its normal or linear operating
point. The recovery time varies, based on whether the
input or output is overdriven and by how much the range
is exceeded. The CLCx050 will typically recover in less
than 30ns from an overdrive condition. Figure 6 shows the
CLC1050 in an overdriven condition.

Input Voltage (V)
Increased phase delay at the output due to capacitive loading can cause ringing, peaking in the frequency response,
and possible unstable behavior. Use a series resistance, RS,
between the amplifier and the load to help improve stability
and settling performance. Refer to Figure 5.

Table 1 provides the recommended RS for various capacitive loads. The recommended RS values result in <=1dB
peaking in the frequency response. The Frequency Response vs. CL plot, on page 6, illustrates the response of
the CLCx050.

Layout Considerations
Comlinear CLC1050, CLC2050, CLC4050 Low Power, 3V to 36V, Single/Dual/Quad Amplifiers
General layout and supply bypassing play major roles in
high frequency performance. Exar has evaluation boards
to use as a guide for high frequency layout and as an aid in
device testing and characterization. Follow the steps below
as a basis for high frequency layout:
• Include 6.8µF and 0.1µF ceramic capacitors for power
supply decoupling
• Place the 6.8µF capacitor within 0.75 inches of the power pin
• Place the 0.1µF capacitor within 0.1 inches of the power pin
• Remove the ground plane under and around the part,
especially near the input and output pins to reduce parasitic capacitance
• Minimize all trace lengths to reduce series inductances
Refer to the evaluation board layouts below for more information.

Evaluation Board Schematics
Evaluation board schematics and layouts are shown in Figures 7-14. These evaluation boards are built for dual- supply operation. Follow these steps to use the board in a
single-supply application:
1. Short -Vs to ground.
2. Use C3 and C4, if the -VS pin of the amplifier is not
directly connected to the ground plane.
